The figure shows an arrangement in which four disks are suspended by cords. The longer, top cord loops over a frictionless pulley and pulls with a force of magnitude 85.2 N on the wall to which it is attached. The tensions in the shorter cords are T1 = 57.4 N, T2 = 42.6 N, and T3 = 7.05 N. What are the masses of (a) disk A, (b) disk B, (c) disk C, and (d) disk D?

A pulley has a negligible mass (that means, the radius is not relevant). It is supported with a pin at the center (and is free to rotate). A rope goes over the pulley. Block A, which has a mass of 5.723 kg is connected to one side of the rope. On the other side, Block B, with a mass of 12.602 kg is connected. The system is released from rest. What is the speed of block B, after B has traveled 0.716 m? Please enter a positive value in m/s (but without units) regardless of the direction of the motion of B
